I can hear my audio wonderful but when I use them on a call; its when its bad. I intended to use these on my cell, which has a protective case, but the 90-degree connector hits case before its fully plugged in. I always get compliments on my shoes when I wear Crocs. The only issue that I have with this product is that the door JUST closes when my shoes are inside. I defiantly would have fit a medium. Due to a medical condition I can no longer wear my high-healed sandals and couldnt find any cute flats. The slats are glued onto the shelves, and appear fairly sturdy. No son nada incómodos, incluso al utilizar lentes no causa molestia alguna y no aprietan la cabeza demasiado ni calan en las orejas. I bought two pairs, both have issues with the stitching coming undone! De buena calidad, pero las enviaron en color negro, y yo las pedí blancas
